Une autre de Billy Wilder...

I put this here because I want to watch it later; it's an hour long.

Writing is very hard work, and having done both writing and directing, I tell you that directing is a pleasure and writing is a drag. Directing can become difficult, but it is a pleasure because you have something to work with. You can put the camera here or there, you can interpret the scene this way or that way, the readings can be such or such. But writing is just an empty page—you start with absolutely nothing. I think writers are vastly underrated and underpaid. It’s totally impossible to make a great picture out of a lousy script. It’s impossible, though, for a mediocre director to completely screw up a great script. –Billy Wilder
